CUDA error cufftplan3d

Hello

Hardware Gigabyte X79-UD3, Intel i7-3930K, GTX-680
Software Debian 11 amd64, running namd3 (a Molecular Dynamics tool: https://www.google.com/search?client=firefox-b-e&q=namd)

While trying a simulation, cuda error, which I do not understand

Code:

FATAL ERROR: CUDA error cufftPlan3d(&forwardPlan, n[2], n[1], n[0], CUFFT_R2C) in file src/CudaPmeSolverUtil.C, function plan3D
 on Pe 0 (gig64 device 0 pci 0:2:0)

Everything as to cuda seems to be OK

Code:

NVIDIA-SMI 470.199.02   Driver Version: 470.199.02   CUDA Version: 11.4

Graphics output from this video card, with various packages (GIM for example) with color quite OK

Thanks for advice

Have you tried compiling some simple CUDA code to see if it's the source or the toolchain?
